Large parts of the Delhi-National Capital Region began Monday under dense fog, with air pollution levels lingering in the moderate to poor range, data from the Central Pollution Control Board (CPCB) showed.
According to CPCB readings, several monitoring stations across the capital recorded elevated AQI levels. Anand Vihar reported an AQI of 242, Bawana 222, Chandni Chowk 217, Dwarka Sector-8 240, and R.K. Puram 232. Other locations included Burari Crossing at 157, DTU 158, IGI Airport (T3) 132, IIT Delhi 141, Jawaharlal Nehru Stadium 194, Lodhi Road 116, Patparganj 207, and Sonia Vihar 208.
Ghaziabad records ‘poor’ air quality as haze spreads across NCR
Neighbouring NCR regions also witnessed hazy conditions during early morning hours. Ghaziabad’s air quality remained in the ‘poor’ category, with an AQI of 259 recorded on Monday morning.
Visibility drops below 50 metres, traffic movement affected
The dense fog led to a sharp decline in visibility across several parts of Delhi and NCR, with sight distances falling below 50 metres at many locations. The reduced visibility disrupted traffic movement on key roads and highways, and officials warned that conditions could worsen as fog continued to persist.
Flights, trains delayed; motorists advised caution on key routes
Transport services were impacted as well, with flight and train operations facing delays at major hubs, including the Indira Gandhi International Airport and prominent railway stations. Authorities urged motorists on busy stretches such as the DND Flyway and the Delhi-Gurgaon Expressway to exercise caution, switch on fog lamps, and keep speeds low.
Western disturbances to bring weather changes later this week
Weather conditions in the capital are expected to evolve over the next few days. From February 3 onwards, skies are likely to gradually clear. However, another western disturbance is forecast to influence north-west India from the night of February 5, potentially bringing cloud cover and light drizzle later in the week.
Forecasts suggest that morning fog will continue for at least the next six days, while daytime temperatures during the first week of February may slowly climb to around 24–25 degrees Celsius, offering slightly warmer afternoons.
Across north India—including Punjab, Haryana, Rajasthan and Uttar Pradesh—two successive western disturbances are expected to trigger noticeable weather changes, with light rainfall likely in parts of north-west India later this week.
